SICOM Display Module (SDM), a component of Spatial Information COMponents (SICOM), can be deployed as a stand-alone independent program (SDM) or as a server (referred to as SDM_Server) that provides GIS services to a client application (referred to as Client). The capabilities and functionality of SDM are described in RITI-SICOM2.0-TECH-99001 and in the SDM user’s manual, RITI-SICOM2.0-TECH-99003. Other than providing GIS services to clients, SDM_Server has the same capabilities and functionality as SDM, and is intended for the developer who is familiar with Visual software development tools such as Visual Basic, Visual C++, Borland Delphi, etc.
In this document, the Microsoft COM services currently implemented by SICOM 2.0’s SDM_server are presented in Section II. The return types and argument types are not necessarily the exact syntax of any particular programming language. They are, instead, suggestive of the type required and must be translated into the specific syntax of the client language. The suggested corresponding methods from the Client side can be found in Section III. In Section IV, a simple test client written in Visual C++ 5.0 is discussed.
